[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] A power distribution cabinet is a device used to centrally manage, distribute and protect power supply. It is usually installed in industrial, commercial and residential buildings to distribute power from the main power supply to various electrical equipment and circuits. A power distribution cabinet usually includes power input terminals, circuit breakers, fuses, grounding circuits, power metering instruments, relays, controllers and other components to ensure safe, stable and reliable power supply.

[0027] Embodiment 1:

[0028] Based on the technical defects of the existing technology that the internal space capacity of the distribution cabinet shell is limited and it is difficult to meet the subsequent expansion and upgrade needs of the equipment, please refer to Figure 1-Figure 6 The utility model provides a sheet metal component for a power distribution cabinet. During subsequent expansion and upgrading, the side panels 31 on both sides are opened, and then the expansion shell 32 is placed on the pallet to increase the capacity inside the cabinet 1, so as to meet the access needs of more electrical equipment, and leave space for future equipment expansion and upgrading, thereby improving the flexibility and expansibility of the power distribution system. The utility model comprises a cabinet 1 and a cabinet door 2 hinged on the front of the cabinet 1, and both sides of the cabinet 1 are provided with expansion components 3 for increasing the internal capacity of the power distribution cabinet; during the initial installation, the expansion component 3 is not installed. When there is a need for expansion due to upgrading, the side panels 31 on both sides are opened, and then the expansion shell 32 is placed on both sides of the cabinet 1 to increase the usable space inside the cabinet 1.

[0029] To achieve the expansion requirements of the internal space of cabinet 1, please refer to Figure 2The expansion component 3 includes a side panel 31 hinged on one side wall of the cabinet 1, and an expansion shell 32 is placed on the side panel 31. The expansion shell 32 is provided with a protrusion 321 at the edge of the side wall of the cabinet 1. A slot 3211 is opened on the side wall of the protrusion 321 and is inserted into the positioning strip 33 through the slot 3211. The positioning strip 33 is fixed to the side wall of the cabinet 1, and a fixing unit 34 installed on the top of the cabinet 1 is provided above the expansion shell 32. After the side panel 31 is opened, the expansion shell 32 can be placed on the side panel 31. When placing the expansion shell 32, the slot 3211 of the protrusion 321 on the expansion shell 32 is aligned with the positioning strip 33 and inserted. Then, the positioning strip 33 is used to horizontally fix and position the expansion shell 32, and the side panel 31 is used to seal the bottom of the expansion shell 32. This ensures that the cabinet 1 and the expansion shell 32 are internally connected and form a closed environment, thereby meeting the space requirements for expansion.

[0030] In order to reduce the amount of material used in the expansion shell 32, the bottom of the expansion shell 32 and the side wall close to the cabinet 1 are both open. In this way, when the expansion shell 32 is used, the side panel 31 can seal the bottom of the expansion shell 32, and the side wall of the expansion shell 32 is connected to the inside of the cabinet 1. This not only meets the upgrade space requirements, but also reduces the use of materials.

[0031] To facilitate fixing the side plate 31 and the expansion shell 32, please refer to Figure 3 The fixing unit 34 includes two studs 341 fixedly connected to the top of the cabinet 1, and nuts 342 are threadedly connected to the studs 341, and a "Z"-shaped fixing buckle 343 is also sleeved on the studs 341. When not expanded, since the side panel 31 is hinged on one side of the cabinet 1, in order to prevent the side panel 31 from opening, the side wall of the fixing buckle 343 is in contact with the side panel 31, thereby limiting the opening of the side panel 31. After expansion, in order to prevent the expansion shell 32 from being pulled out upward, the bottom of the fixing buckle 343 is in contact with the top of the expansion shell 32, thereby limiting the movement of the expansion shell 32, which can fix both the side panel 31 and the expansion shell 32.

[0032] In order to prevent excessive stress on the hinged position between the side panel 31 and the cabinet body 1, support baffles 4 in contact with the bottom surface of the side panel 31 are fixedly provided on both side walls of the cabinet body 1. The support baffles can support the side panel 31, thereby reducing the stress on the connection between the side panel 31 and the cabinet body 1.

[0033] To facilitate heat dissipation, heat dissipation holes 5 located inside the support cover 4 are opened on both side walls of the cabinet 1, and air can enter and exit the cabinet 1 through the heat dissipation holes 5 to achieve heat dissipation.

[0034] Embodiment 2:

[0035] After the cabinet 1 is installed, the electrical equipment needs to be installed in the cabinet 1. After installation, wiring work needs to be done. However, due to the obstruction of the electrical equipment, there will be some inconvenience in wiring on the front. To solve this problem, please refer to Figure 4 On the basis of the first embodiment, two limit blocks 6 are fixedly provided on the top of the cabinet 1, and a rear cover 7 is buckled on the limit blocks 6. The rear cover 7 is covered on the back of the cabinet 1. When routing, the rear cover 7 can be removed, and then the routing can be carried out from the back of the cabinet 1, which is more convenient. After the routing is completed, the rear cover 7 can be buckled on the limit blocks 6 again.

[0036] Through the above embodiments, it can be known that: during the initial installation, the expansion component 3 is not installed. When there is a need for expansion due to upgrading, the side panels 31 on both sides are opened, and then the slots 3211 of the protrusions 321 on the expansion shell 32 are aligned with the positioning strips 33 and inserted. Then, the positioning strips 33 are used to laterally fix and position the expansion shell 32. At this time, the expansion shell 32 can be placed just on the side panels 31, and then the bottom of the fixing buckle 343 is in contact with the top of the expansion shell 32, and the nut 342 is used to lock it, and the expansion shell 32 can be installed, so as to achieve the effect of expanding the internal space of the cabinet 1.

[0037] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
